or pivot shaft 40. Shaft 40 pivotally supports by an offset hingearrangement-4L- see Fig. 1-a pair of combination covers and arms 42.These arms rotatably support shafts 43 and each of said shafts mounts apressing and feeding roll 44 knurled as at 45. These rolls arepositioned-in spaced and parallel relation and the spacing therebetweenmay be varied, although in so varying the same, the rolls are varied'rlative to the spacing between them and the applying roll 20. The tworolls 44 rotate in the same.

direction. 7

An arm 46 is socketed asat 47 and a clamp 48 detachably mounts a bracket49 supporting an aligning guard .and guide 50. The bars 51 of thebracket 49'are slidable in'the openings 47 and are locked thereinrby theclamp screw 48 to position the guard and guide 50, so that the.predetermined width of adhesive is applied to the strip in its passagebetween the. applying roll and the two pressing and feeding rolls. v i

The feeding and pressing rolls are-yieldingly mounted and normallyconstrained toward contact with the applying'roll and by means ofsprings 52. The same, however, are preventedfrom such contact byadjust.- able stops 53. The feeding rolls, therefore, are free fromadhesive.

The power for driving the pressing and feeding rolls is derivedfrom theapplying roll so that the same are operable in timed relation. The shaft13 mounts a pulley 54 which lies in the same plane as pulleys55 carriedby the shafts 43. The housing is provided with elongated slots 56,through which the shafts extend and into the housing 11. The housingenclosed ends mount the pulleys 55. Each of said pulleys has more than180 degrees of contact with the belt. The endless belt 57 runs uponanidler pulley 58, pivotally supported on arm 59 pivoted at 60. Associatedwith the shaft 60 is an arm 61 and a coil spring 62 is connected to thefree end thereof as at 63 and anchored to the housingas at 64. Thespring 62 nor1nally tends to'rock the arm 61 counterclockwisesee Fig.3for loweringthe tensioning pulley 58.'f01 obtaining the desired drivingtension in the belt.- The motor 15, therefore, not only rotates shaft 13for rotating the applying roll, which in turn by frictional contactrotates the transfer roll, but also through the pulley 54 frictionallydrives the feeding and pressing rolls 44.

The invention claimed is:- 1. A gluing machine including an adhesiveapplyingroll arranged to support an end and edgewise presented sheet ofmaterial while passing thereover and adhesive is applied to theunderface thereof, a pair of spaced sheet engaging and sheet conveyingpressing rolls positioned lthereover, and each rolls and supporting theouter ends thereof and means supporting the opposite ends of said rollsand said supports; 3 r 1 2. A*device -of the-character described,comprising a base, a housing extending u wardlythereof and intermediatethe en s,

a stationary overhanging arm extending therefrom, a pair of feedingrolls rotatably mounted, means associated with the arm and housing andpivotally supporting the rolls and permitting roll movement toward andaway fromeach other, an applying roll therebeneath and in juxtapositionthereto, a standard for one end of the applying roll, said standard andarm supporting said rolls .to permit end and edgewise'presentationof asheet, an adhesive container. positioned therebeneath, a transfer rollmounted therein and normally constrained towardapplying rollengagementand rotatable thereby, an electric motor mounted on the baseopposite from the-container, and balancing said overhanging arm, andpower meansoperable by the motor for rotating the applying roll androtating the feeding rolls. 7

3.- In a marginal adhesive applying ma chine, the combination of a;base, a housing extending upwardly thereof, an overhanging arm supportedby the housing parallel to thebase, a power shaft-supported at one end.by the housing, a standard terminating below thelevel of the arm andsupporting the other end of the shaft, anap- I.

a pair of parallel and spaced, feeding rolls supported by the housingand arm, means normally-constraining said rolls toward each other andtoward the applying roll, means pivotally supporting said feeding rollsupon 7 an axis lying in a plane intermediate said rolls and includingthe axis of the applying roll, adjustable stop means limiting thepivotal movementof said feeding rollstoward each other and-preventingapplying roll contact, a pulley coaxial with each of said rolls,a'nendlessbelt operatively'associated withnot-less than 180 degrees ofcontact with each of said pulleys, and meansnormally tensioning saidbelt.

4. In. a marginal adhesive applying device of the character described,the combinafixed relationtothe arm, said container having an openinginits upper portion through which the applying roll projects, and atransfer roll yieldingly mounted in said container and normallyconstrained into applying roll engagement.

5. In a marginal adhesive applying device of the character described,the combination of an overhanging arm, pressure applying means supportedthereby, a container detacha-bly mounted beneath the arm and meansincluding a hinged cover for access, an applying roll rotatablysupported in fixed relation to the arm, said container having an openingin its upper portion through which the applying roll projects, atransfer roll yieldingly mounted in said container and normallyconstrained into applying roll engagement, and means operativelyassociated with said transfer roll and arranged for overlapping theapplying roll for scraping the same at the sides thereof and aligningthe transfer roll therewith.

In witness whereof, I have hereunto afiixed my signature.
